我正在Android上构建一个水提醒应用程序，并希望每天安排一定数量的警报，在特定时间（由用户设置）后停止，并在第二天重新启动，而无需用户打开该应用程序。我该怎么做呢

我不知道如何设置重复警报，因为我希望它们在某一点停止，第二天重新启动，而重复警报不能做到这一点。如何实现这一点？

您可以设置两个警报，第一个是用于提醒的重复警报。

另一个警报用于在特定时间停止第一个警报，然后安排第二天的警报

您可以设置两个警报，第一个是用于提醒的重复警报。

另一个警报用于在特定时间停止第一个警报，然后安排第二天的警报

这是我的示例代码。这可能对你有帮助，但我不确定

主要活动：

public static int NOW_NOTIFICATION = 101; 

Intent intent = new Intent(MainActivity.this, NotificationReceiver.class);
                intent.putExtra(NotificationReceiver.NOTIFICATION_MESSAGE, "Sample Alert");
                PendingIntent pendingIntent = PendingIntent.getBroadcast(
                        MainActivity.this, NOW_NOTIFICATION, intent, PendingIntent.FLAG_ONE_SHOT);

                cancelNotification(NOW_NOTIFICATION);
                AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
                alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()
                        + (2 * 1000), pendingIntent);
